| Low Power Consumption : 7A (VOUT=2V TYP.) Operating Voltage Range : 3.0V ~ 10.0V Output Voltage Temperature Coefficient : -3900ppm/ (TYP.) SOT-25 and USP-6B Packages APPLICATIONS Mobile phones Portable AV equipment Palm top computers, PDAS Battery powered equipment GENERAL DESCRIPTION The XC31B series are ultra small CMOS temperature sensor ICs. As a bandgap type temperature sensor is built-into the XC31B, linearity, in comparison to thermistor type temperature sensors, is much better. The operating temperature range of the series is from -30 to +80. The XC31B comes in a mini molded SOT-25 and USP-6B packages with a supply current of only 7A (@VOUT=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 100mV increments within a range of 2.0V to 6.0V (at 25). FEATURES Operating Voltage Range Output Voltage Range Output Voltage Accuracy Detectable Temperature Range Low Power Consumption : 3.0V ~ 10.0V : 2.0V~ 6.0V : 3% : -30 ~ +80 : 7A (@VOUT=2.0V) Output Voltage Temp.

PIN CONFIGURATION PIN ASSIGNMENT PIN NUMBER SOT25 USP-6B 1 2, 5 6 4 3 1 PIN NAME NC VSS CE VOUT VIN FUNCTION No Connection Ground Chip Enable Output Power Supply VSS NC CE VIN NC VOUT 2 3 4 5 *The dissipation pad for the USP-6B package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS pin.

If this IC is to be used in applications where such currents are required, please use a buffer on the output *3: Output voltage temperature coefficient (TD) is defined as: TD= V OUT Ta V OUT emax Tse Ta *4: Linearity margin error (TL) is calculated as follows: TL= where emax = maximum error. The maximum error is the maximum difference between the actual measured value and the value on an approximated straight line. 1110 XC31B Series TYPICAL APPLICATION CIRCUIT NOTE ON USE 1. When the load capacitance CL is too large, oscillation may occur on the output signal. 2. Output signal overshoot will occur when the power (VIN) is switched on or when the power drastically fluctuates. The chip enable (CE) function is effective for helping to avoid overshoot and also in saving consumption current. 1111 XC31B Series TYPICAL PERFORMANCE CHARACTERISTICS (1) Output Voltage vs. Ambient Temperature XC31BPN20A2.0V XC31BPN40A4.0V (2) Supply Current vs. Ambient Temperature XC31BPN20A2.0V XC31BPN40A4.0V (3) Output Voltage vs. Input Voltage XC31BPN20A2.0V XC31BPN40A4.0V 1112 XC31B Series TYPICAL PERFORMANCE CHARACTERISTICS(Continued) (4) Input Transient Response 1 (5) Input Transient Response 2 (6) CE Pin Transient Response 1113 XC31B Series TYPICAL PERFORMANCE CHARACTERISTICS(Continued) (7) Ripple Rejection Rate 1114 |
